Transcription

1 RFL inline filters are designed for inline mounting in hydraulic and lubrication systems. Inline Filter RFL Cast version Volume rates up to 1300 l/min* Pressure range 25/40 bar * For larger flow rates, please see brochure: RFL Inline filter, welded version

2 1. TECHNICAL SPECIFICATIONS 1.1. FILTER HOUSING Construction All filters are subject to the Pressure Equipment Directive 97/23/EC and are classified in Article 3, Paragraph 3. The filters consist of a two-piece filter housing with a screw-on cover plate. This two-part construction enables the inlet and outlet to be positioned either one above the other, or at different heights on opposite sides. Vent, drain and clogging indicator ports are standard FILTER ELEMENTS Original HYDAC filter elements guarantee reliable function and protection from wear for contamination-sensitive hydraulic components and systems. HYDAC filters are validated and their quality is continuously monitored according to the following standards: DIN ISO 2941: Verification of collapse/burst resistance DIN ISO 2942: Verification of fabrication integrity and determination of first bubble point DIN ISO 2943: Verification of material compatibility with fluids ISO 3724: Verification of flow fatigue characteristics ISO 3968: Evaluation of pressure drop versus flow characteristics ISO 4572/ISO16889: Multi-pass method for evaluating filtration performance In addition to guaranteeing retention and flow rate characteristics, the filter elements have excellent structural stability. The careful construction and mechanically stable support of the filter media guarantee aboveaverage beta value stability and flow fatigue characteristics of the filter elements. The filter elements are available with the following collapse/burst stability values: Betamicron / Aquamicron (BN/AM) : 10 bar Betamicron (BN3HC) : 25 bar Aquamicron (AM) : 10 bar Paper (P/HC) : 10 bar Wire mesh (W/HC) : 30 bar Stainless steel fibre (V) : 30 bar 1.3.

5 5. FILTER CALCULATION / SIZING The total pressure drop of a filter at a certain flow rate is the sum of the housing p and element p. The pressure drop can be determined either with the aid of our Filter Sizing Program FSP, which is available free of charge, or by using the following graphs P-Q HOUSING GRAPHS BASED ON ISO 3968 The housing graphs apply to mineral oil with a density of 6 kg/dm 3 and a kinematic viscosity of 30 mm 2 /s. In this case, the differential pressure changes proportionally to the density. In each case p is given for the largest possible flange nominal width. 0 0 RFL 661/662/851/ P-Q GRAPHS - FILTER ELEMENTS The element graphs apply to mineral oil with a kinematic viscosity of 30 mm 2 /s. The pressure drop changes proportionally to the change in viscosity (see example 5.3.).
